Preparation method and application of porous inner core for large ceramic core with high porosity and high strength
The invention discloses a preparation method and application of a porous inner core for a large ceramic core with high porosity and high strength. The preparation method of the inner core comprises the following steps: step 1, uniformly mixing inorganic powder; step 2, adding the mixed powder into a plasticizer to prepare slurry; 3, porous sponge is used as an inner core template; step 4, immersing an inner core template into the slurry, and shaping; 5, the shaped inner core template is rapidly dipped in the slurry for secondary shaping; 6, sintering the inner core green body subjected to secondary shaping; and 7, the sintered inner core is strengthened. By means of the method, the ceramic core which is high in porosity, high in strength and easy to separate out can be prepared, and the strength performance and the dissolution performance of large and heavy ceramic cores can be more flexibly regulated and controlled. In addition, the weight of the ceramic core can be greatly reduced, and the ceramic core industry is led to develop towards a lighter trend.
本发明公开了一种高气孔率、高强度的大型陶瓷型芯用多孔内芯的制备方法及应用，其中所述内芯的制备包括：步骤1：将无机粉体混合均匀；步骤2：将混合粉体加入到增塑剂中，制备成浆料；步骤3：利用多孔海绵作为内芯模板；步骤4：将内芯模板浸入到浆料中，并进行定型；步骤5：将定型后的内芯模板快速蘸取浆料进行二次定型；步骤6：将二次定型后的内芯生坯进行烧结；步骤7：对烧结后的内芯进行强化。通过本发明的方法不仅可以制备出一种具有高气孔率、高强度、易脱出的陶瓷型芯，也可以实现大型、厚重类陶瓷型芯在强度性能和溶出性能上更为灵活的调控。此外，本发明还可以极大地降低陶瓷型芯的重量，引领陶瓷型芯行业朝向更加轻质化趋势发展。
